I am seriously considering a new F 250, 7.3L XLT, SC, SB, 4x4 tow pkg, camper prep, 5er prep, etc. I am currently pulling a 2250RK @6500lbs (max 7k) and realize that this 250 is more than enough but not completely educated yet on the pros/cons of the three rears: 4.30, 3.73, and 3.55. My local dealership (largest F series dealer in the U.S.) seems to like the 4.30 b/c the vast majority of the model described above on their lots are 4.30. My current minimal knowledge is only that it seems that, for example, the 4.30 would provide more pulling power while towing from the start / from a light, etc, but not provide great MPG while at home pulling empty as a daily driver. All additional experience and input would be greatly appreciated. Tks in advance.

I would go with the 3.73 , this is the middle and will still give you plenty of pulling power as well as a little better when not towing , unless you are thinking of upgrading the RV next then you may want to size the truck accordingly.

You will achieve the best fuel economy with the 3.55:1 and with your current load and with the 7.3L gas you would have no issues pulling anywhere. If you would commonly load up your rig close to the GVWR and also load the truck and commonly tow, I would also consider the 3.73:1.
I pull an Imagine 2600RB with a 5.3L with a 3.42:1 rear axle, 6 speed and while more power would always be great, I have no issues as an example. And we will never buy a larger rig. To know where your headed with a rig will help to make a decision.
With your heavier truck, and similar towing loads, the additional torque of the 7.3L, the 10 speed, and a 3.55:1 you will have excellent towing for your rig and the best fuel economy while not towing.
Fuel prices are already moving up and most likely will continue to do so. With the 3.55:1 running empty you can expect 15mpg. Towing your lighter rig may deliver about 11mpg.
